Out of the box and in direct comparison to my various holders and docks for my old HTC Sensation I noticed the fine workmanship and choice of materials. Unlike some other, equally expensive, mount the bracket iBolt is much better. In particular, the joint head, the ever squeaks my anchor bracket and wobbles while driving, makes a firmer and quietschfreien impression.
The phone may be inserted with or without additional cases in the dock. Personally, I have no case, but can report that the material of the bracket to the HTC One X is well disposed and no scratches or marks will be left. It slides well into the bracket and is very easy to pull it out again.
Thanks to the clip which is folded down to secure, the phone sits neatly laid. According to the manufacturer (and videos on YouTube) allows the holder vibration-free ride.
(I will report in the next few days if this can be confirmed.)
The price deters perhaps, but I can safely recommend this bracket currently for every owner of a HTC One X. For other devices, the manufacturer fixtures available!

Supplement, 12/08/2012: After a few rides and video recordings while driving, I can confirm the absence of vibrations! At first I assumed that the joint head, which is apparently easy to move by hand, would be adjusted while driving. Fortunately, I was taught! The complete recording one sees no unusual vibrations. Very good!
